Why do some MKV Files work fine on a PC but go unrecognized when you scan library

files?

Can you provide a specific example including the kind of library you set up, and the filename?

[Plex Documentation](https://support.plex.tv/articles/) → [Your Media](https://support.plex.tv/articles/categories/your-media/)  
→ [Naming & Organizing Your TV Show Files](https://support.plex.tv/articles/naming-and-organizing-your-tv-show-files/)  
→ [Naming & Organizing Your Movie Files](https://support.plex.tv/articles/naming-and-organizing-your-movie-media-files/)

You must follow Plex naming requirements. Otherwise, it will be difficult (or impossible) for Plex to recognize and organize the files.

Optionally, place the files in an Other Videos library. Plex will not try to match them to an online database, download artwork, descriptions, etc.

There are tools that can help with naming and organization. Here’s a shortlist. The free version of Tiny Media Manager works for most people.

- [Filebot](https://www.filebot.net/)
- [Tiny Media Manager](https://www.tinymediamanager.org/)
- [Microsoft PowerTools PowerRenamer](https://github.com/microsoft/PowerToys)

Many people use Filebot. It is quite powerful and can rename an entire library in minutes.

Tiny Media Manager is also very useful, and free.

Example TMM Renamer Patterns:

- Show Name: `${showTitle} (${showYear})`
- Season: `Season ${seasonNr2}`
- Episode Name: `${showTitle} (${showYear}) s${seasonNr2}e${episodeNr2} ${episode.title}`
- Movie Name: `${title} (${year}) {imdb-${imdb}}`

PowerRenamer in Microsoft Power Tools is helpful for simple renaming with pattern matches or regular expressions. It makes quick work of tasks such as adding a year to file names, removing undesirable text from multiple file names, etc
